Engine Performance problem
1987 Mercedes Benz 420sel V8 Two Wheel Drive Automatic 206000 miles
My car all of a sudden has started to idle real high. In the range of 1500 to 2000 rpms. I noticed the thermal vacume valve was broke and then I started to check all the other vacume lines and they seemed to be ok. I replaced the thermal vacume valve and it still idles high. And the same time that happened the anti-lock brack light has come on and the electric fan stays on now. I purchased a thermal switch for that as well and will replace that too. But the idle is still way to high. What could it be. Thanks Derrick
have the same problem?
